In the given figure, AB is parallel to CD. Angle PRB = 82 degrees. What is the value (in degrees) of angle QSC?
Show answer & explanation
Correct answer: C
Explanation
Given:
AB ∥ CD, ∠PRB = 82°
Alternate angles are equal, and vertically opposite angles are equal.
∠PRB = ∠RSB = 82° (Alternate angles)
∠RSB = ∠QSC = 82° (Vertically opposite angles)
